Velocity Chart Explained

Velocity charts are a simple tool that measures the pace at which teams get work done. There are many forms of the velocity chart, and each's purpose is to help you measure how much work your team can accomplish in a given iteration.

The collection frequency depends on which velocity chart you're looking at. For the legacy Flash charts (charts not on the Dashboard or Reports tab), these charts collect data at midnight as defined by the workspace timezone. The rest of the reports collect data in near real time, within ten minutes of a change being committed. Apps can collect data on either parameter, depending on which data source is being used to display the data.

Velocity charts are dynamic. If you move a story out of the iteration after it ends, the results of the chart will change.

How It Is Calculated

The answer depends on which chart we are examining.

In the legacy Flash chart found on the Plan, Timeboxes page:

The green bars show the total amount of accepted work delivered by the last day of the iteration.

In the standard Velocity Chart (found on the Reports tab and Dashboard):

Dark green bars show the total amount of accepted work delivered by the last day of the iteration.

Light green bars (if present) show the total amount of accepted work delivered since the last day of the iteration.

Red bars (if present) represent work done during the iteration that was not accepted.
